SWITCH-BAR-ADJUSTING DEVICE.

Specification of Letters Patent.

Application filed July 1, 1909. Serial'No. 505,306.

To all whom it may concern:

Be it known that I, JOHN E. CONLEY, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented a certain new and useful Improvement inSwitch-Bar-Adjusting Devices, of which the following is a specification.

My invention relates to switch bar adjusting devices, and has for itsobject to provide a new and improved device of this description.

The invention is illustrated in the accompanying drawings, whereinFigure 1 is a side elevation of one form of device embodying theinvention; Fig. 2 is a plan view of the device shown in Fig. 1; Fig. 3is a sectional View taken on line 3--3 of Fig. 1; Fig. 4: is a view ofthe adjustable piece by which the adjustment is made.

It is desirable in the use of railway switches to adjust the switchpoint with its associated rail.

One of the objects of the present device is to provide a simple, cheapand eflicient means for securing this result.

Referring now to the drawings, I have shown the switch point 1 and therail 2 with which it is associated. The switch point is connected to theadjustable support 3 in any desired manner as by means of the bolts 4..The adjustable support 3 is adjustably connected with the controllingpart 5 so that it may be adjusted with relation thereto, to vary theposition of the switch :point 1. As herein shown, the adjustable Supportand controlling part 5 are connected together by an adjustable piece 6.The adjustable piece 6 fits into an opening in the controlling part 5,and has a supporting part 7 which rests upon the controlling part 5.This supporting part is preferably provided with one or more projections8 which fit into openings in the controlling part 5. Said adjustablepiece is provided with a hole 9 eccentrically located. The adjustablesupport 3 is preferably provided with two separated portions 10 betweenwhich the controlling part is received. These separated portions areprovided with holes 11 adapted to register with the eccentric hole 9.The parts are firmly connected together by means of a bolt 12, whichpasses through the holes 11 and 9. WVhen the parts are thus fastenedtogether, there is a rigid connection between them, and no danger of anyrelative movement. The adjustable support as shown in the drawing has aportion formed into a loop, into which is received the controlling partand the adjustable piece.

When it is desired to adjust the switch point, the bolt l2-is removed,and the separated portions 10 (see Fig. 3) moved to one side so as tofree the adjustable piece 6. This adjustable piece is then lifted so asto disengage the projections 8, and is then turned to get the desiredadjustment. The turning of this adjustable piece varies the position ofthe eccentric hole 9, moving it forward or backward with relation to thecontrolling piece 5. Then the desired amount of adjustment is secured,the projections 8 are inserted in the holes in the controlling part, andthe separated portions 10 moved back into posit-ion, and then moveduntil the holes 11 register with the hole 9. The bolt 12 is then placedin position, the nut tightened, thus locking the parts in this adjustedposition. It will thus be seen that any desired amount of adjustment maybe secured, that this adjustment may be easily and quickly made, andthat after the parts are in position, there is no chance of any relativemovement thereof. It will further be seen that this arrangement forms asimple construction which cannot get out of order or become deranged. Inpractice there are two switch points, one at each side, each having anadjusting device associated with it.

I claim:

1. The combination with a switch point of an adjustable supportconnected therewith, a controlling part, an adjustable pieceintermediate the adjustable support and the controlling device, and afastening device which passes through all three parts to hold them inplace, said adjustable piece having a concentric connection with thecontrolling part, and an eccentric connection with the fastening device.

2. The combination with a switch point of an adjustable supportconnected therewith, a controlling part, said adjustable supportprovided with two separated parts between which the controlling part isreceived, an adjustable piece also contained between said separatedparts, means for preventing the rotation of said adjustable piece, and afastening device passing through all the parts .and eccentricallyconnected with the adjustable piece.
